Juan Lagares: He could have trade value for a team wanting to build with speed, defense and youth. Oh, wait, isn’t that what the Mets want to do?

Curtis Granderson: His power is in decline and he has three years and $47 million left on his contract. Sure, the Mets would like to deal him. But, who would take on that contract and what could you get?

Jeurys Familia, Jenrry Mejia and Bobby Parnell: Three power arms in the bullpen would attract interest. However, Parnell is coming off an injury that hurts his value. But, haven’t the Mets been wanting to build a bullpen for four years now?

Unquestionably, a healthy Troy Tulowitzki makes the Mets a better team. I read something again today about the Mets dealing for him, but if you are a true fan of the team you know that’s not how they do business.

TULO: Just wishful thinking.

The last star the Mets traded for was Johan Santana, but they were closer to winning then than they are now. Plus, it is debatable how that trade worked out.

At 30, Tulowitzki is still in him prime and last year’s numbers of .340, 21 homers, 52 RBI, .432 on-base percentage and 1.035 OPS through 91 games before he was injured make a compelling argument for breaking the bank.

However, if you’re a true Mets fan – and I assume most of you are – then you also know “the bank,’’ is the franchise’s North Star. Tulowitzki is owed $129 million over the next seven seasons and to the Mets’ line of thinking, that number supersedes those at the plate.

And, we haven’t gotten to the part yet about the Rockies’ demands. Sorry, but Daniel Murphy and Dillon Gee – both of whom the Mets would love to trade because of their salaries, which combined are less than $13 million – won’t cut it. This isn’t talk-radio fantasy land when you give up nothing for a star.

At least two of those young arms the team is building around have to be included. There is also the possibility that to make this deal Tulowitzki’s contract would be modified. He has a clause that prohibits him being traded more than once, so, if the Rockies deal him the Mets would not be allowed if they believe the contract is a burden. At least, not without a cost.

A red flag is Tulowitzki’s injury history, which has prevented him from playing more than 140 games only once since 2009.

If the Mets were really on the cusp, then go for it. However, there are too many variables that scream this is not the right player at the right time. The Mets finally rid themselves of burdensome contracts and are making themselves competitive again.

But, the Mets are more than willing to trade Dillon Gee, Bartolo Colon and Jon Niese. The common denominators are they are at the back of the Mets’ rotation and make the most money.

Another common thread is none are expected to bring much in return, which means don’t anticipate anything happening. At least, anything of significance.

Two will be the Opening Day rotation because Syndergaard won’t be brought up prior to June to preserve his Super Two status. Bet on it being Niese and Colon, with Gee possibly going to the bullpen in long relief.

However, at $5 million, that’s steep for the bullpen, and more so for the minor leagues.

With other options, both of the trade and free-agent variety available in the market, teams could shy from Niese ($36.5 million over four years if both options are picked up) and Colon ($11 million).

Niese’s contract, injury history and mediocrity make him especially hard to trade.

If the Mets move any of the three, it might be more likely to happen at the trade deadline.

Operating under the assumption Matt Harvey will be ready for spring training and subsequently the start of the season, there will undoubtedly be an innings limitation.

In theory, the Mets want him ready for a postseason push. They haven’t announced what the cap would be, but let’s figure on 175-180 innings – which is at least three starts shy of the hoped for 200.

So, what are their options?

The first is to do nothing and let him pitch … pitch … and pitch. Undoubtedly, that’s Harvey’s choice, but it won’t happen. Why risk another injury?

Another is to pitch him without game or innings restrictions, then cut him in September if the Mets aren’t in contention. However, if they go that route and the Mets are in the race, they would be doing a disservice to their players and fans, and actually the integrity of the game because they wouldn’t be putting their best team on the field.
That’s not ideal, and neither is the pick-and-choose method, which would be to juggle him with off days and selected starts.

Also, not preferred is to pull him if the Mets are winning late in a game. Harvey will moan about this, and his noise would be amplified if the Mets’ bullpen blew the game.

One option because of the off days in April and the high probability of bad weather is to bag that month entirely or at least the first two weeks.

On the positive, it would keep him out of the cold weather. On the negative, he would still pile up innings in extended spring training games.

Finally, and I think it is the best – it’s something the Nationals didn’t do with Stephen Strasburg – is to have their figure in mind from the start and schedule accordingly.

That would mean making a schedule for the entire season and not deviate. Rainouts would only help the Mets because it would push him back.

In this format, the Mets could schedule skip days now for Harvey and not go on the fly. In addition, they could put him a rigid innings cap, but that would irritate him and lead to an occasional blown save.

However, if the Mets and Harvey knew from the outset his cap would be seven innings both parties could plan accordingly.

Harvey wouldn’t necessarily have to pace himself and Collins would know his bullpen options before the game started. They would accept the blown save as part of the deal.

This format would require discipline from Collins and acceptance from Harvey, which would be more likely because there wouldn’t be any surprises.

Like it or not, this is the hand the Mets have been dealt and must play.

In addition, they might consider plans for Jacob deGrom and Zack Wheeler.

All of this proves the cliché “you can never have too much pitching.’’

As frustrating as this might be, the Mets are set up for this complicated option because they have Rafael Montero, Carlos Torres and sometime in June, Noah Syndergaard. They also have depth with Jon Niese, Bartolo Colon and Dillon Gee.
